Hi Nanc
I've just been through the process of creating a blog. I signed up for a course through
Coursera. I've done loads of courses with them and they're usually excellent. However,
the Create a Website in a weekend was truly pants ! But Youtube does have some good
tutorial content.
The best advice I got was to look through a series of blogs that you like and then use that style.
Then on a piece of paper, using a pencil, lay out how you'd like it to look, how people will navigate
around etc. I've ended up using Wordpress.org's' Twenty Ten theme hosted at Wordpress.com.
I chose this after reading Maggie's excellent blog

It does seem to be difficult to change the layout of a theme so, pick a theme you're happy with.
( Which seems to the advice given for choosing a partner ! )
When I've got a little more content I'll post it up on here, unless you want to see what an
embryo blog looks like !
